POWDER-CHARGIlYtG DEVICE.

I r all whom it may) concern:

Beit known that I, HARRY D. SrrrLnY, a citizen of the 'United' States, resldln at Albia, inqthe county of Monroe and tate f Iowa, have invented certain new and use -fuli Improvements in Powder-Charging Devices, iof whichthe following is a specification, reference being had to the accompany ingsdrawings."

'Th-isjnvention relates to an improved powder "charging device, and has for its primary object to provide a device prlmarlly designed" for use by miners in charging a i hole or bore formed in the face of the mine walllwith powder, and then securely tampfing the hole. I

It-isanother and more particular object 1 of'the invention-to provide a device for the above purpose embodying a tubular member "to; receive the powder charge and the dynamite'cartridge or other explosive, a tubular i rod "connected to said member, an expelling 1 fplunger arranged within said tubular" mem- 1 her, an operating rod therefor provided with a Scraper disk, and means for locking said rod against movement relative to the tubular rod to retain said plunger against movement .for use as-a tamping head, or to permit of l) ,theuse of the scraping disk.

v 'It is also a; further general object of my inventionto providea devicefor the above purposewhichisrelatively simpleand duj rable ingitsconstruction, as well as efiicient 'and 'reliable'in operation, and capable of 'f'manufacture at comparatively small cost. v With the above and other objects in view, the inventio'niconsists in the improved comf' bination, construction and relative arrangement of' ithef several-parts as will be herein {after more fully described, subsequently -claimed' and illustrated in the accompanying; drawings in which similar reference characters designate corresponding parts throughout the several views, and wherein I Figure 1 is a sidefelevation, the tubular.

' Application filed August 10, 191 8. Serial No. 249,271.

These arms are pivotally engaged upon the bolts -7 fixed in opposite sides of asleeve 8, which is threaded upon one end of a tubular rod 9. This rod may be made up in sections of suitable length, coupled together, 7

and is provided at its other end with a sleeve 10 having a tapered threaded bore 11;

A rod 12 {is longitudinally movable through the'tubular rod Sand to one end of this rod, a plunger'13 is pivotally connectedyas at 14, said plunger being freely movable within the tubular charge receiving member 5. This plunger 13 may be of any preferred construction.

The other end of the rod 12 is threaded and to the same acoupling member 15 is connected. The other end of said member is exteriorly threaded for engagement by the interior threads on one end of the sleeve .16 in which one end of the rod 17 is threaded.

The other end of this rod isformed with a disk-shaped scraper blade 18, which projects at right angles to said rod and from one side thereof/ '5 1 In theme of the device, the rod 12'=is movedlongitudinally through the rod 9 and the member=15 is threaded into-thetapered bore 11 of the sleeve 10, thereby locking the rods 9 and 12 'againstrelative -movement, then the device maybe used as a scraping tool, as will be hereinafter set forth. 'In the boring of the hole to receive the explosive charge, the loosened material is scraped or removed from the hole by means of the scraper blade 18 in the manner illustrated in Fig. e of the drawings. After the hole has been bored to the proper depth, the member 15 is rotated to unlock the rod 12, which is then moved through the rod 9 to position the plunger 13 in the inner end of the tubular member 5. The explosive powder and the dynamite cartrid e, together with a suitable tampin materia, are then arranged in the member 5 The tubular member 5 devised" an improved powder charging' and; tampingf device for use abyzminers giwhich I; will be 'veryfservieeable and convenient: in. practicalf use and. will "eliminate the lnef ces-a 'forced throughthe'jrod 9 to causethe plunger 13 to expel or eject the'mat'erials into the inner end ofthe hole. f'lher'odu 12 is now again locked, as above explained,

against movement'relative to the rod 9,'vvith: the plunger 13 projecting slightly beyond threaded axially on the" other endj'of the the outer end of'the member 5.7' The'pluiii ger may now be conveniently used for] the Purpose of packing or'tamping the hole, after which said tubular member is .-;With-g drawn. Thus it will be seenthat I have sity of employing a number .of.;sepai'ate tools or implements." The device asa Whole is comparatively simple in its construction, as Well as strong'and durable, and can also" '20 be manufactured; and sold 7 at relatively small cost. It will, of course, be understood; that the charge receiving member- 5';

Well as the rods 8". and 12 can-be-"of any idesired length anddiameter.)
